[vdr] [PATCH] re-use devices in transfer mode

Hi!

Consider the scenario: - 2 devices, 1 used in transfer mode on transponder A - a new recording / streamdev session starts on transponder A

Now, IMO the correct thing to do is start the new receiver in the transfer-moded device, so that the second device is left free.

However, the usual "use-already-tuned-devices" check in GetDevice() only checks for device->Receiving(), which does not report transfer-moded device, resulting in the new receiver being started on second device, thus both devices being reserved for receiving data from the same transponder.

Attached is a patch for GetDevice() to check for transfer-moded devices as well.
